As an optimization, if this type can never hold a Gc
pointer and trace
is unnecessary to
call, you may implement this method and return false. The default implementation returns
true, signaling that Collect::trace
must be called. Read more
Must call Collect::trace
on all held Gc
pointers. If this type holds inner types that
implement Collect
, a valid implementation would simply call Collect::trace
on all the
held values to ensure this. Read more
